What Are the Key Differences Between Chubb and CNA Professional Liability (E&O) Insurance?

Professional-Service Classes

Chubb says Pro ERM is available to non-licensed professional-services firms and lists examples such as consultants, event planners, marketing and PR firms, printers, and staffing firms. CNA’s MPL target list includes consultants, staffing firms, advertising agencies, and event planners, while noting that the list is not a complete eligibility rule. A buyer in one of these fields can compare how each company describes its target class, then verify acceptance for the actual services. [1] [3]

E&O Product Grouping

Chubb describes Pro ERM as a single policy combining professional liability, media, and cyber exposures. [1] CNA’s Epack 3 brochure describes a modular combination of technology and professional liability with cyber and media. [4] CNA’s current cyber page separately describes EPS Plus as E&O with cyber for professional-services firms. [3] The published structures differ in how they group these lines; neither description supplies the terms of a buyer’s issued form.

  • Ask Chubb whether the Pro ERM target class and service definition fit your operations. [1]
